The name "Sinox" was chosen initially as our company and product name, a play on ‘sinus’ and ‘chlorine dioxide’. Since it sounded a bit more medical/medicinal that's how our (old) packaging came out. It was a nice looking brand, and memorable too. There were, though, some negative associations: Sinox is also the name of a registered pesticide brand, and we were always concerned that someone would confuse us with "Vick's Sinex", an antihistamine (drug) spray.
So we did another name search and ended up on Snoot. Ironically it was right where we started a couple of years ago: Snoot was the name that we used on the original product concept. Everyone just assumed that we wouldn't use the name, and that it wasn't even available for trademark. Not so, as it turns out, and the USPTO awarded us the trademark to "Snoot!" last year. We had our excellent creative team, led by Gabrielle Raumberger of EPOS, come up with a new look, and we incorporated the feedback that we had gotten from thousands of customers into our messaging. We're very happy with the new brand. People have told us that they miss the Sinox Spray name, and in some ways we do too.
One of the most important things that branding experts tell you is that the brand should match the experience. Sinox looked kind of like a drug, and that's sort of what people would expect from it. Snoot! looks much more like a cleanser/health-aid, and that's exactly what it is.
